Ответ:
[tex] - 1 \frac{121}{180} [/tex]
Пошаговое объяснение:
[tex](4 \frac{9}{2} - 3 \frac{6}{5} ) \div ( - \frac{18}{7} )[/tex]
[tex]4 \frac{9}{2} - 3 \frac{6}{5} = 1 \frac{45 - 12}{10} = 1 \frac{33}{10} = 4 \frac{3}{10} [/tex]
[tex]4 \frac{3}{10} \div ( - \frac{18}{7} ) = \frac{43}{10} \times ( - \frac{7}{18} ) = - \frac{301}{180} = - 1 \frac{121}{180} [/tex]
